If it turns out to be a selinux issue (which by now it does appear to be),
I'd rather not disable selinux, but rather debug the context issues...
I just found some selinux errors in /var/log/messages:

Here is the output of the sealert command:
sealert -l 0de6d349-55f3-4ae2-aa9b-cfa3228e9c32

It sounds like this might be helpful for me:

I guess I'll give it a shot and see what happens... Does anyone want to
weigh in on whether I should try "touch /.autorelabel; touch
/BackupData/.autorelabel; reboot" since the file system in question is
mounted to /BackupData, not '/' ?
